Computer simulation of bias recording

The technique of AC bias recording is explained by a newly developed theoretical approach. It is demonstrated that the model can explain the physical background of the linearization of the remanence curve and be used to determine the dependence of the maximum output level (MOL) on various technical and media parameters. The merits and drawbacks of changes in the different media data are evaluated quantitatively by computer simulation. All theoretical results are compared with corresponding experimental data and thus verified
